ABSTRACT

Any groundwater lowering system will need, to some degree, monitoring and maintenance measures to ensure effective operation. This chapter describes the methods commonly used for monitoring of groundwater lowering works, including the use of dataloggers and automatic control systems. Maintenance issues are also discussed, as are methods of sealing boreholes on completion. The problems of corrosion, encrustation, and biofouling, which sometimes result in the gradual deterioration of system performance, are described.
